Title:
SOLAR CELL MODULE
Document Type and Number:
WIPO Patent Application WO/2021/079807
Kind Code:
A1
Abstract:
The present invention provides a solar cell module in which: cracks of cells (30) are reduced even when a thin front surface glass layer (10) is used; foam remaining after vacuum lamination and separation between a second sealing layer (40) and a rear surface protection layer (50) after DH are suppressed; and further, load resistance is high. The present invention is specifically a solar cell module provided with, in order from the light-receiving surface side, a front surface glass layer (10) having a thickness of 0.4-1.6 mm, a first sealing layer (20), cells (30), a second sealing layer (40), and a rear surface protection layer (50), the solar cell module being characterized in that the rear surface protection layer (50) has, in order from a side close to the second sealing layer (40), a first easy adhesion resin layer (51) having adhesion properties with the second sealing layer (40), a second resin sheet layer (52) having a bending elastic modulus of 1500-4000 MPa, a foamed third resin layer (53) having a bending elastic modulus of 200-1000 MPa, and a fiber-reinforced fourth resin layer (54) having a bending elastic modulus of 10000-45000 MPa.
